Failed to setup Custom Domain for APIM using PowerShell script - azure-powershell

Question

I am trying to setup custom domain for my APIM instance using below script
[CmdletBinding()]
param (
[String]
$ResourceGroupName,
[String]
$Hostname,
[String]
$ApimServiceName,
[string]
$KeyVaultId
)
$ProxyHostnameConf = New-AzApiManagementCustomHostnameConfiguration -Hostname $Hostname -HostnameType "Proxy" -KeyVaultId $KeyVaultId -DefaultSslBinding
$apim = Get-AzApiManagement -ResourceGroupName $ResourceGroupName -Name $ApimServiceName
$apim.ProxyCustomHostnameConfiguration = $ProxyHostnameConf
Set-AzApiManagement -InputObject $apim
But the script is failing with below error
Line |
15 | Set-AzApiManagement -InputObject $apim
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| 'SubnetResourceId' does not match expected pattern
| '^/subscriptions/[^/]*/resourceGroups/[^/]*/providers/Microsoft.(ClassicNetwork|Network)/virtualNetworks/[^/]*/subnets/[^/]*$'.
I am getting this error both in my local machine as well as from the devops Microsoft hosted agent

I was able to fix this using azure cli command mentioned in the below ink
Azure CLI - Bash script to set up API Management custom domain
[CmdletBinding()]
param (
[String]
$ResourceGroupName,
[String]
$HostName,
[String]
$KeyVaultId,
[String]
$ApimServiceName
)
$config ='[{\"hostName\":\"'+$HostName+'\",\"type\":\"Proxy\",\"keyVaultId\":\"'+$KeyVaultId+'\",\"defaultSslBinding\":true,\"negotiateClientCertificate\":false}]'
Write-Host $config
az apim update --resource-group $ResourceGroupName --name $ApimServiceName --set hostnameConfigurations=$config
